PayPal PHP Class Library Demo / Sample Code

Demo Kit Info
These demo kits offer a more complete demonstration of how the different checkout flows with PayPal
work.
Make sure to check /samples and /templates which are included free with the library and are often all
you need
to understand how things work. The samples are functional, but are only setup for one call at a time.

The demo kits available here are more complete and tie together a number of APIs within a
basic shopping cart interface so that you can see how to tie everything together.

Express Checkout

Basic

Here we are integrating Express Checkout without any line item details or any extra
features. We obtain the user's shipping information so that we can calculate shipping
and tax, but otherwise no additional data is included with this checkout demo.
